Three aircraft pass an Air India jet while at enroute altitude. Lest anyone think these are “close calls”, RVSM-equipped aircraft are permitted to operate with 1,000 foot vertical separation.

If you’re wondering how the captain (this is being shot from the left seat, judging by the angle of the windows) knew to get his camera rolling in time to film this, the onboard TCAS system will display its targets overlaid onto the nav display/EHSI, so there is no mystery about where everyone is, relative to each other.
